File this under: cool robots. Robots, more specifically, Swiss quadrotor robots, may soon rule the world, and this video shows why - "researchers at ETH Zurich are teaching them to play catch." Let's just say that they're quickly become self-aware and able to learn on their own. Continue reading for the video and more information.

Using a net strung between three quadrotors, the researchers deployed algorithms that not only allow the bots to toss a ball both to themselves and to another team of hovering quadrotors, but also allow them to learn in realtime. When their accuracy fails them, the quadrotors learn from their mistake and adjust their trajectory on the next try. So after a series of failed tosses, the robots eventually compensate to get it right.
